HPJ - lithium battery Mfr (Possible Google contract)

0

We know that CBAK didn't win the Google contract because CBAK ceo said they didn't. So that leaves a fair amount of chance that it could be HPJ:

HPJ develops, manufactures, and markets a range of lithium-ion rechargeable batteries and lithium polymer rechargeable batteries for various applications, such as laptops, digital cameras, and wireless communication products.
